WHY Choose us

1,Over 25 years experience in oil pressing equipment field, ranking first in Jinan,China.

2, Cooperate with Jinan Machine Design Research Institute and Jinan University of Technology in the oil equipment, protein extraction, phospholipid extraction,etc. R&D and application of new technology.

The techmology of my company for pretreatment and pre-pressing which mainly include the cleaning , decrustation extrusion,flaking,cooking and pre-pressing and so on .Considering the different characteristic of oil seeds and the customer requirements,we can provide you the special design,in order to adjust the oilseed to the optimun state ,which will improve the oil yield and the cake quality.

Pretreatment process feature:

1)Different combinations of process can process various oil plants in one workshop.

2)Use special intensified pretreatment technology for aroma peanut oil to make it more aroma.

4)Extrusion treatment is used for raw materials with hard extraction, large-sized powder, and large capacity, which can reduce residual oil and solvent consumption, and increase the capacity by 50-80%.

5)The new technology of shelling and low-temperature treatment can ensure high protein and least denaturation.

5) The new technology of shelling and low-temperature treatment can ensure high protein and least denaturation.

â¢ Use the second steam of desolventizer toaster and remaining steam from steam jet pump as the heat source of the first steam, which can save energy, reduce the condenser configuration area and save investment.

â¢ Due to the low temperature of the steam, the crude oil features light color, good quality and low residual solvent.

I. Low temperature with thick alkali:

Adjust the oil temperature to 20~30â, then put in 20~30Be alkali liquor in 5~10 minutes, and stir it about 20~60 minutes on condition of 60r/m. Increasing the temperature slowly when notice the separate of neatsoap after reacted, 1â per minute, when it reach 60â, stop stiring, keep still and make soap feet settlement, it will takes nearly 6~8 hours, then let out the soapstock.

â ¡. High temperature light alkali operation:

Firstly,determine the alkali thickness in accordance with the alkali value of crude oil(according to the table below), account the alkali and water added in, when the alkali value is under 5, for each unit acid value, the total water added into per ton oil is 23 kg. When the alkali value is over 5, no more than 12% of the oil heavy, the exceeded alkali is only 0.005~0.002%.

â ¢. Washing:

After releasing the nigre, grease heated up to boom 90â, then add in the hot water for washing, stirring. Water temperature should be about 5 ~ 10 â higher than the oil temperature, for low water temperature tends to emulsification. After adding the water, continue to stir for 5 minutes, then rest 4 hours for precipitation, and release the soap water, wash 2 ~ 3 times depending on the oil quality and decide. Washed oil slowly heated up to 105â, stirred dehydration for 1 hour, washed oil can also direct inhaled decoloring pot and vacuum drying 30 minutes.
